LOGGING
Let's run in the pseudo-distributed cluster the same job we had in local mode. You put
the input file into HDFS using the
hadoop fs
command. Submit the job for running
using the same
hadoop jar
command as in local mode.
The first thing you'll notice is that you no longer have the torrent of messages on
your console. You only get a measure of progress in the map phase and reduce phase,
and the same summary of counters at the end as in local mode. You can see this in
Figure 6.2
In pseudo-distributed mode, the console only outputs a job's progress and its counters at
the end.
